I am knocking it apart AGAIN today, Having a conversation with Rick who has just finished this job, I failed to compare old and new bearing measurements. That will be the first thing I do. That being said, and ASSUMING the bearings match, I have come to the conclusion that there is not enough shim in the pinion. According to Deve"s directions, add .010 shim to the old shim pack as a start. When I disassembled the rear, I found someone had been in it previously. Most notably there was no gear oil in it, and multiple marks on the retainer ring. Who knows if they assembled it correctly or put correct tolerances back together. Does anyone remember how much shim they used for their finally assembly? I am going to take a swing and probably double the shim pack I currently have installed. My thought process being that the shims are what hold the bearing from bottoming out in the torque tube. The farther rearward the front bearing sits, the farther rearward the pinion gear sits. This should allow the pinion not to bind when the retaining bolts are tightened and allow for the spacing, and removal of the spacing tool. Any shim depth info would be greatly appreciate and save me from another 100x of disassembly.
